IMPROVEMENT IN TOY MOTORS.

Specification forming part of Letters Patent No. 212,926, dated March 4, 1879 application filed January 15, 1879.

To all whom it may concern- Be it known that I, HENRY GRoTE, of the city, county, and State of New York, have invented a new and useful Improvement in Toy Motive Power, of which the following is a specification Figure 1 is a top view of my improved device. Fig. 2 is a detail section of the same, taken through the line a: m, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish a toy motive power for giving motion to dancing figures, toy hand-organs, and other mechanical toys, which shall be so constructed that the uncoiling of the impelling-cord will coil a spring, the uncoiling of which will recoil the impelling-cord, ready to be again used.

The invention consists in a toy motive power, formed by the combination of the flywheel its pins, the sleeve, the cords, the drum, and the coiled spring with each other and with the frame-work, as herein after fully described.

A represents a small frame, which is supported upon legs B, of any convenient length. 0 is a fly-wheel, the ends of the journals of which are pointed and revolve in the ends of two pins, 1). One of the pins D is made long to receive a sleeve, E, upon the inner end of which are formed clutch'tecth, to engage with clutch-teeth formed upon the journal of the flywheel C. To the middle part of the sleeve E is secured the end of a cord, E, which is wound around the outer part of the said sleeve E. The free end of the cord E passes through a hole in a side bar of the frame A, which hole should be about opposite the middle of the outer half of the sleeve E, so that when the outer end of the cord F also causes the said cord to rewind itself upon the sleeve E evenly and smoothly.

To the middle part of the sleeve E is attached the end of the cord G, which is coiled around, and its other end is attached to a drum, H. The cords F G may be a single cord, secured at its middle part to the sleeve E.

The drum .H revolves freely upon a pin, I, attached to the frame A, and to its hub is attached the inner end of a coiled spring, J, the outer end of which is attached to theframe A. The cord G is wound in such a direction around the drum I-[ that the unwinding of the cord F from the sleeve E will wind the cord G upon the said sleeve and coil up the spring J so that when the cord F is released the uncoiling of the spring J will rewind the cord Gr upon the drum H, and the cord F upon the sleeve E, ready to be again drawn upon to give another impulse to the fly-wheel C. To

the hub of the flywheel O are attached one or more pulleys K, to receive belts for giving motion to the desired toy or toys.

I am aware that it is not new to revolve a box by a chain on drum, and to rotate a flywheel in the same direction by a pawl within the box, said box (on the removal of pressure) being carried by a recoil of spring, that rewinds the chain upon the drum while the fly-wheel continues to revolve but What Iclaim as new, and of my invention, 1s

A toy motive power formed by the combination of the flywheel O, its pins D, the sleeve E, the cords F G, the drum H, and the coiled spring J with each other and with the frame A B, substantially as herein shown and described.
